Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Standard histopathological examination to confirm higher fluorescent signals in tumour tissue compared to normal tissue. - Calculating target to background ratios in fluorescence images obtained during and directly after the surgical procedure and fluorescence images obtained during ex vivo analyses in bread loaf slices and in histological slices (odyssey scanner, fluorescence microscopy). - Determining the tracer distribution at microscopic level using needle based confocal laser endomicroscopy during ex vivo off table imaging. - Measuring fluorescent signal using spectroscopy to correct for scattering. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Intraoperative assessment of positive margins based on fluorescent images. - Off table imaging of surgical specimen directly after excision to identify positive margins, lymph nodes and metastases based on ex vivo fluorescent images. - Back table imaging of surgical specimen after excision to identify tumour tissue by NIR endoscopy based on ex vivo fluorescent images . | — |
